1st question: Haven't really counted how many...every day find something new, like the one above (which greggy is giving me a copy free). I have a spreadsheet that tracks them, maybe I'll count later.
2nd question: Why I collect them, I've collected comics since I was 6 (I'm 29 now) and my collection grew too large. Had to focus my collecting habits. My last tour in the military was in the 82nd Airborne Division....thought it'd be nostalgic to collect trooper books.
My very first book was actually a Fantastic Four #295, I still have that. But since everyone and their mother are collecting Marvel FF/Spidey/Hulk etc. I thought I'd try something different. Plus I can directly relate to the Paratrooper/War books that I am buying. The stories are sometimes telling stories of the times in which they were printed. Not only that, I don't think these GA/SA war books get the attention that they deserve. Everyone is collecting the superhero books, but pay no attention to these obscure non-key books. I've been drinking too much beer again, I'll answer these questions in my thread when I'm more clear headed.
